UNSPSC 51203401 Azathioprine is a Commodity code that designates a specific pharmaceutical product—an immunosuppressant medication used in transplant and autoimmune disease management. Recent state and local procurement activity under this code shows that jurisdictions source azathioprine through piggyback pharmaceutical contracts and cooperative purchasing vehicles, typically for stockpiling, emergency preparedness, or routine community health operations. The work spans routine pharmaceutical supply orders placed by state departments of public health and county health authorities, with vendors fulfilling requests through established warehouse distribution networks and quarterly or as-needed delivery schedules.

Activity under this code concentrates in Illinois and Florida based on recent opportunities. The Illinois Department of Public Health awarded a pharmaceutical warehouse piggyback contract through the MMCAP Infuse consortium to Chartwell Rx LLC (IFB 26482DPHPREPDB53392, awarded August 28, 2026) for pharmaceutical products including related immunosuppressants; the contract runs 12 months with renewal options through year 3 and totals $2,999,999.11 across all renewal periods. Seminole County, Florida released an IFB (IFB60459723LAS, posted June 30, 2026) for naloxone and drug deactivation systems with quarterly deliveries, indicating that state and local agencies use cooperative purchasing and competitive bidding to fill pharmaceutical and health-supply pipelines. The code shows limited recent direct activity; most opportunities under azathioprine itself flow through piggyback and cooperative purchasing agreements rather than standalone RFPs or IFBs.
